This invention relates to methods comprising administering a FAK inhibitor and an immunotherapeutic agent such as anti-PD-1 or anti-PD-L1; that are useful in the treatment of abnormal cell growth, such as cancer, in mammals, especially humans.

RELATED APPLICATIONS

The present application claims priority under 35 U.S.C. § 119(e) to U.S. provisional patent application, U.S. Ser. No. 62/186,197 filed Jun. 29, 2015, which is incorporated herein by reference in its entirety.

FIELD OF INVENTION

This invention relates to methods of treatment of a disease or disorder described herein (e.g., abnormal cell growth (e.g., cancer)), comprising administering to a subject (e.g., a human subject) a FAK inhibitor and an immunotherapeutic agent.

BACKGROUND OF INVENTION

Convincing evidence suggests that focal adhesion kinase (FAK), i.e., PTK2, a cytoplasmic, non-receptor tyrosine kinase, plays an essential role in cell-matrix signal transduction pathways (Clark and Brugge 1995, Science 268: 233-239) and its aberrant activation is associated with an increase in the metastatic potential of tumors (Owens et al. 1995, Cancer Research 55: 2752-2755). FAK was originally identified as a 125 kDa protein highly tyrosine-phosphorylated in cells transformed by v-Src. FAK is encoded by the PTK2 gene in humans. FAK was subsequently found to be a tyrosine kinase that localizes to focal adhesions, which are contact points between cultured cells and their underlying substratum and sites of intense tyrosine phosphorylation. FAK is phosphorylated and, thus, activated in response to extracellular matrix (ECM)-binding to integrins. Recently, studies have demonstrated that an increase in FAK mRNA levels accompanied invasive transformation of tumors and attenuation of the expression of FAK (through the use of antisense oligonucleotides) induces apoptosis in tumor cells (Xu et al. 1996, Cell Growth and Diff. 7: 413-418). In addition to being expressed in most tissue types, FAK is found at elevated levels in most human cancers, for example in highly invasive metastases. For example, U.S. Pat. No. 8,247,411 relates to a broad class of novel pyrimidine derivatives that are kinase inhibitors, and more specifically, inhibitors of FAK. Compounds such as these may be useful in the treatment of abnormal cell growth.

Cancers can be recognized by the immune system, and regulate and even eliminate tumors. Immune checkpoints refer to a plethora of inhibitory pathways that help maintain self-tolerance and modulate the duration and amplitude of physiological immune responses in peripheral tissues in order to minimize collateral tissue damage. Tumors co-opt certain immune-checkpoint pathways as a mechanism of immune resistance, particularly against T-cells that are specific for tumor antigens. The development of checkpoint blocking antibodies, e.g., inhibitory receptors, that target or are directed against, e.g., cytotoxic T-lymphocyte antigen 4 (CTLA-4) and programmed death 1 receptor (PD-1), can facilitate the treatment of a disease or disorder described herein (e.g., abnormal cell growth, e.g., cancer (e.g., a cancer described herein)). CTLA-4 and PD-1 can function as negative regulators and have non-redundant roles in modulating immune responses. They are expressed on tumor-specific T-cells and can lead to compromised activation and suppressed effector functions e.g., profileration, cytokine secretion, and tumor cell lysis. CTLA-4 can attenuate the early activation of naïve and memory T-cells. PD-1 is involved in modulating T-cell activity in e.g., peripheral tissues, e.g., via interaction with its ligands, i.e., PD-L1 and PD-L2. Blockers of the immune checkpoint pathway (e.g. anti-PD-1, anti-PD-L1, anti-CTLA-4,) can enhance antitumor immunity and provide opportunities to treat a disease or disorder described herein (e.g., abnormal cell growth, e.g., cancer (e.g., a cancer described herein)), e.g., provide more effective treatment for subjects suffering from cancer.

Although durable responses to single agent immune checkpoint inhibitors have been reported, additional approaches are needed to extend this therapeutic benefit to a greater proportion of cancer patients. Accordingly, substantial efforts are ongoing to identify agents that can augment T-cell mediated killing of tumor cells and potentiate the effects of checkpoint inhibitors. Focal Adhesion Kinase (FAK) and the closely related family member PYK2 are potentially valuable targets in this regard due to the roles of these enzymes in regulating key cellular populations in the tumor microenvironment. FAK inhibitors may increase cytotoxic T-cells (CD8+ expressing cytotoxic T-cells) in tumors, and decrease the immune cell populations that suppress the host anti-tumor immune response (T-regs, M2 tumor associated macrophages, myeloid-derived suppressor cells). FAK inhibitors can turn up the PD-1/PD-L1 immune checkpoint pathway and may augment anti-tumor efficacy of various anti-tumor immunotherapies. A combination of a cancer therapy (e.g., a FAK inhibitor) with a cancer immunotherapy (e.g. anti-PD-1, anti-PD-L1, anti-CTLA-4), may enhance the generation and effectiveness of tumor-specific cytotoxic lymphocytes and provide a promising approach for more effectively treating a disease or disorder described herein (e.g., abnormal cell growth, e.g., cancer (e.g., a cancer described herein)). The compounds described herein, e.g., FAK inhibitors, may be used in combination with an immunotherapy described herein, to prevent and treat a disease or disorder described herein, e.g., abnormal cell growth (e.g., a cancer described herein).

DETAILED DESCRIPTION OF THE INVENTION

Described herein are methods for treating abnormal cell growth, e.g., cancer, e.g., a cancer described herein, the method comprising administering a FAK inhibitor and a cancer immunotherapy. Applicants have discovered that treatment of a subject suffering from abnormal cell growth, e.g., cancer, with a FAK inhibitor in combination with a cancer immunotherapy, more effectively prevents and treats abnormal cell growth, e.g., cancer, than with either agent alone.

Methods of Treatment and Administration

The methods described herein relate to treating a human subject suffering from a disease or disorder described herein (e.g., abnormal cell growth, e.g., cancer (e.g., a cancer described herein)) with a FAK inhibitor in combination with a cancer immunotherapy. Administered “in combination”, as used herein, means that two (or more) different treatments are delivered to the subject during the course of the subject's affliction with the disorder, e.g., the two or more treatments are delivered after the subject has been diagnosed with the disorder and before the disorder has been cured or eliminated or treatment has ceased for other reasons. In some embodiments, the delivery of one treatment is still occurring when the delivery of the second begins, so that there is overlap in terms of administration. This is sometimes referred to herein as “simultaneous” or “concurrent delivery”. In other embodiments, the delivery of one treatment ends before the delivery of the other treatment begins. In some embodiments of either case, the treatment is more effective because of combined administration. For example, the second treatment is more effective, e.g., an equivalent effect is seen with less of the second treatment, or the second treatment reduces symptoms to a greater extent, than would be seen if the second treatment were administered in the absence of the first treatment, or the analogous situation is seen with the first treatment. In some embodiments, delivery is such that the reduction in a symptom, or other parameter related to the disorder is greater than what would be observed with one treatment delivered in the absence of the other. The effect of the two treatments can be partially additive, wholly additive, or greater than additive. The delivery can be such that an effect of the first treatment delivered is still detectable when the second is delivered.

In some embodiments, the method comprises administration of a FAK inhibitor before administration of a cancer immunotherapy. In some embodiments, the method comprises administration of a FAK inhibitor after administration of a cancer immunotherapy. In some embodiments, the method comprises administration of a FAK inhibitor concurrently with administration of a cancer immunotherapy. In some embodiments, the FAK inhibitor is VS-4718 (PND-1186), VS-6063 (PF-04554878; defactinib), VS-6062 (PF-562271), VS-5095, GSK2256098 or BI 853520.

Abnormal Cell Growth

The methods described herein are directed to the treatment or prevention of abnormal cell growth in a subject (e.g., a human subject). Abnormal cell growth, as used herein and unless otherwise indicated, refers to cell growth that is independent of normal regulatory mechanisms (e.g., loss of contact inhibition). This includes the abnormal growth of: (1) tumor cells (tumors) that proliferate, for example, by expressing a mutated tyrosine kinase or overexpression of a receptor tyrosine kinase; (2) benign and malignant cells of other proliferative diseases, for example, in which aberrant tyrosine kinase activation occurs; (3) any tumors that proliferate, for example, by receptor tyrosine kinases; (4) any tumors that proliferate, for example, by aberrant serine/threonine kinase activation; and (5) benign and malignant cells of other proliferative diseases, for example, in which aberrant serine/threonine kinase activation occurs. Abnormal cell growth can refer to cell growth in epithelial (e.g., carcinomas, adenocarcinomas); mesenchymal (e.g., sarcomas (e.g. leiomyosarcoma, Ewing's sarcoma)); hematopoetic (e.g., lymphomas, leukemias, myelodysplasias (e.g., pre-malignant)); or other (e.g., melanoma, mesothelioma, and other tumors of unknown origin) cells.

In some embodiments, the method is effective in treating non-hematolotic malignancies. In some embodiments, the method is effective in treating pancreas, non small cell lung carcinoma (NSCLC), small cell lung carcinoma (SCLC), mesothelioma, melanoma, breast and ovarian cancer. In an embodiment, the breast cancer is triple-negative breast cancer (e.g., breast cancer which does not express the genes for the estrogen receptor, progesterone receptor, and Her2/neu). In an embodiment, the lung cancer is non-small cell lung cancer (NSCLC), e.g., KRAS mutant NSCLC. In an embodiment, the ovarian cancer is advanced ovarian cancer (e.g., advanced ovarian cancer or metastatic ovarian cancer). In an embodiment, the method is effective in treating mesothelioma (e.g., malignant pleural mesothelioma, e.g., surgically resectable malignant pleural mesothelioma).

Neoplastic Disorders

Abnormal cell growth can refer to a neoplastic disorder. A “neoplastic disorder” is a disease or disorder characterized by cells that have the capacity for autonomous growth or replication, e.g., an abnormal state or condition characterized by proliferative cell growth. An abnormal mass of tissue as a result of abnormal cell growth or division, or a “neoplasm,” can be benign, pre-malignant (carcinoma in situ) or malignant (cancer).

Exemplary neoplastic disorders include: carcinoma, sarcoma, metastatic disorders (e.g., tumors arising from prostate, colon, lung, breast and liver origin), hematopoietic neoplastic disorders, e.g., leukemias, metastatic tumors. Treatment with the compound may be in an amount effective to ameliorate at least one symptom of the neoplastic disorder, e.g., reduced cell proliferation, reduced tumor mass, etc. Cancer

The inventive methods of the present invention may be useful in the prevention and treatment of cancer, including for example, solid tumors, soft tissue tumors, and metastases thereof. The disclosed methods are also useful in treating non-solid cancers. Exemplary solid tumors include but are not limited to, malignancies (e.g., sarcomas, adenocarcinomas, and carcinomas) of the various organ systems, such as those of lung, breast, lymphoid, gastrointestinal (e.g., colon), and genitourinary (e.g., renal, urothelial, or testicular tumors) tracts, pharynx, prostate, and ovary. Exemplary adenocarcinomas include but are not limited to, colorectal cancers, renal-cell carcinoma, liver cancer (e.g., Hepatocellular carcinoma), non-small cell carcinoma of the lung, pancreatic (e.g., metastatic pancreatic adenocarcinoma) and cancer of the small intestine.

The cancer can include mesothelioma; neurofibromatosis; e.g., neurofibromatosis type 2, neurofibromatosis type 1; renal cancer; lung cancer, non small cell lung cancer; liver cancer; thyroid cancer; ovarian; breast cancer; a nervous system tumor; schwannoma; meningioma; schwannomatosis; neuroma acoustic; adenoid cystic carcinoma; ependymoma; or ependymal tumors. In some embodiments, the cancer exhibits decreased merlin expression and/or mutation, and/or deletion and/or promotor hypermethylation of the NF-2 gene. In an embodiment, the cancer is mesothelioma that exhibits decreased merlin expression and/or mutation, and/or deletion and/or promotor hypermethylation of the NF-2 gene.

In some embodiments, the cancer is renal cancer.

The cancer can include cancers characterized as comprising cancer stem cells, cancer associated mesenchymal cells, or tumor initiating cancer cells. The cancer can include cancers that have been characterized as being enriched with cancer stem cells, cancer associated mesenchymal cells, or tumor initiating cancer cells (e.g., a tumor enriched with cells that have undergone an epithelial-to-mesenchymal transition or a metastatic tumor).

The cancer can be a primary tumor, i.e., located at the anatomical site of tumor growth initiation. The cancer can also be metastatic, i.e., appearing at least a second anatomical site other than the anatomical site of tumor growth initiation. The cancer can be a recurrent cancer, i.e., cancer that returns following treatment, and after a period of time in which the cancer was undetectable. The recurrent cancer can be anatomically located locally to the original tumor, e.g., anatomically near the original tumor; regionally to the original tumor, e.g., in a lymph node located near the original tumor; or distantly to the original tumor, e.g., anatomically in a region remote from the original tumor.

The cancer can also include for example, but is not limited to, epithelial cancers, breast, lung, pancreatic, colorectal (e.g., metastatic colorectal, e.g., metastatic K Ras mutated), prostate, head and neck, melanoma (e.g., N Ras mutated locally advanced or metastatic malignant cutaneous melanoma), acute myelogenous leukemia, and glioblastoma. Exemplary breast cancers include but are not limited to, triple negative breast cancer, basal-like breast cancer, claudin-low breast cancer, invasive, inflammatory, metaplastic, and advanced Her-2 positive or ER-positive cancers resistant to therapy.

Immunotherapy

The methods described herein comprise administering a FAK inhibitor and an immunotherapy to a subject having abnormal cell growth. Exemplary immunotherapies include, but are not limited to the following.

In some embodiments, the immunotherapeutic agent is a compound (e.g., a ligand, an antibody) that inhibits the immune checkpoint blockade pathway. Cancer immunotherapy refers to the use of the immune system to treat cancer. Three main groups of immunotherapy used to treat cancer includes cell-based, antibody-based, and cytokine therapies. All groups exploit cancer cells' display of subtly different structures (e.g., molecular structure; antigens, proteins, molecules, carbohydrates) on their surface that can be detected by the immune system. Cancer immunotherapy (i.e., anti-tumor immunotherapy or anti-tumor immunotherapeutics) include but are not limited to, immune checkpoint antibodies (e.g., PD-1 antibodies, PD-L1 antibodies, PD-L2 antibodies, CTLA-4 antibodies, TIM3 antibodies, LAG3 antibodies, TIGIT antibodies); and cancer vaccines (i.e., anti-tumor vaccines).

Cell-based therapies (e.g., cancer vaccines), usually involve the removal of immune cells from a subject suffering from cancer, either from the blood or from a tumor Immune cells specific for the tumor will be activated, grown, and returned to a subject suffering from cancer where the immune cells provide an immune response against the cancer. Cell types that can be used in this way are e.g., natural killer cells, lymphokine-activated killer cells, cytotoxic T-cells, dendritic cells, CAR-T therapies (i.e., chimeric antigen receptor T-cells which are T-cells engineered to target specific antigens), TIL therapy (i.e., administration of tumor-infilrating lymphocytes), TCR gene therapy, protein vaccines, and nucleic acid vaccines. An exemplary cell-based therapy is Provenge. In some embodiments, the cell-based therapy is a CAR-T therapy.

Interleukin-2 and interferon-alpha are examples of cytokines, proteins that regulate and coordinate the behavior of the immune system.

Antibody therapies are antibody proteins produced by the immune system and that bind to a target antigen on the surface of a cell. Antibodies are typically encoded by an immunoglobulin gene or genes, or fragments thereof. In normal physiology antibodies are used by the immune system to fight pathogens. Each antibody is specific to one or a few proteins, and those that bind to cancer antigens are used, e.g., for the treatment of cancer. Antibodies are capable of specifically binding an antigen or epitope. (Fundamental Immunology, 3^(rd) Edition, W.e., Paul, ed., Raven Press, N.Y. (1993). Specific binding occurs to the corresponding antigen or epitope even in the presence of a heterogeneous population of proteins and other biologics. Specific binding of an antibody indicates that it binds to its target antigen or epitope with an affinity that is substantially greater than binding to irrelevant antigens. The relative difference in affinity is often at least 25% greater, more often at least 50% greater, most often at least 100% greater. The relative difference can be at least 2-fold, at least 5-fold, at least 10-fold, at least 25-fold, at least 50-fold, at least 100-fold, or at least 1000-fold, for example.

Exemplary types of antibodies include without limitation human, humanized, chimeric, monoclonal, polyclonal, single chain, antibody binding fragments, and diabodies. Once bound to a cancer antigen, antibodies can induce antibody-dependent cell-mediated cytotoxicity, activate the complement system, prevent a receptor interacting with its ligand or deliver a payload of chemotherapy or radiation, all of which can lead to cell death. Exemplary antibodies for the treatment of cancer include but are not limited to, Alemtuzumab, Bevacizumab, Bretuximab vedotin, Cetuximab, Gemtuzumab ozogamicin, Ibritumomab tiuxetan, Ipilimumab, Ofatumumab, Panitumumab, Rituximab, Tositumomab, Trastuzumab, Nivolumab, Pembrolizumab, Avelumab, durvalumab and pidilizumab.

Checkpoint Blocking Antibodies

The methods described herein comprise, in some embodiments, treating a human subject suffering from a disease or disorder described herein, the method comprising administering a composition comprising a cancer immunotherapy (e.g., an immunotherapeutic agent). In some embodiments, the immunotherapeutic agent is a compound (e.g., an inhibitor or antibody) that inhibits the immune checkpoint blockade pathway Immune checkpoint proteins, under normal physiological conditions, maintain self-tolerance (e.g., prevent autoimmunity) and protect tissues from damage when the immune system is responding to e.g., pathogenic infection Immune checkpoint proteins can be dysregulated by tumors as an important immune resistance mechanism. (Pardo11, Nature Rev. Cancer, 2012, 12, 252-264). Agonists of co-stimulatory receptors or antagonists of inhibitory signals (e.g., immune checkpoint proteins), provide an amplification of antigen-specific T-cell responses. Antibodies that block immune checkpoints do not target tumor cells directly but typically target lymphocyte receptors or their ligands to enhance endogenous antitumor activity.

Exemplary checkpoint blocking antibodies include but are not limited to, anti-CTLA-4, anti-PD-1, anti-LAG3 (i.e., antibodies against lymphocyte activation gene 3), and anti-TIM3 (i.e., antibodies against T-cell membrane protein 3). Exemplary anti-CTLA-4 antibodies include but are not limited to, ipilimumab and tremelimumab. Exemplary anti-PD-1 ligands include but are not limited to, PD-L1 (i.e., B7-H1 and CD274) and PD-L2 (i.e., B7-DC and CD273). Exemplary anti-PD-1 antibodies include but are not limited to, nivolumab (i.e., MDX-1106, BMS-936558, or ONO-4538)), CT-011, AMP-224, pembrolizumab (trade name Keytruda), and MK-3475. Exemplary PD-L1-specific antibodies include but are not limited to, BMS936559 (i.e., MDX-1105), MEDI4736 and MPDL-3280A. Exemplary checkpoint blocking antibodies also include but are not limited to, IMP321 and MGA271.

T-regulatory cells (e.g., CD4+, CD25+, or T-reg) are also involved in policing the distinction between self and non-self (e.g., foreign) antigens, and may represent an important mechanism in suppression of immune response in many cancers. T-reg cells can either emerge from the thymus (i.e., “natural T-reg”) or can differentiate from mature T-cells under circumstances of peripheral tolerance induction (i.e., “induced T-reg”). Strategies that minimize the action of T-reg cells would therefore be expected to facilitate the immune response to tumors. (Sutmuller, van Duivernvoorde et al., 2001).

In some embodiments, the compounds (compounds described herein, e.g., a FAK inhibitor) and compositions (e.g., compositions comprising a compound described herein, e.g., a FAK inhibitor) are used with a cancer immunotherapy (e.g., a checkpoint blocking antibody) to treat a subject (e.g., a human subject), e.g., suffering from a disease or disorder described herein (e.g., abnormal cell growth, e.g., cancer (e.g., a cancer described herein)).

In some embodiments, the additional treatment (e.g., an additional cancer treatment) can be administered simultaneously (e.g., at the same time), in the same or in separate compositions, or sequentially. Sequential administration refers to administration of one treatment before (e.g., immediately before, less than 5, 10, 15, 30, 45, 60 minutes; 1, 2, 3, 4, 6, 8, 10, 12, 16, 20, 24, 48, 72, 96 or more hours; 4, 5, 6, 7, 8, 9 or more days; 1, 2, 3, 4, 5, 6, 7, 8 or more weeks before) administration of an additional treatment (e.g., a compound or therapy). The order of administration of the first and secondary compound or therapy can also be reversed.

The methods of the invention may be used or administered in combination with one or more additional therapies (e.g., cancer treatment, e.g., surgery, additional drug(s) or therapeutic agents) for the treatment of the disorder/diseases mentioned.

In addition to being able to be administered in combination with one or more additional therapies (e.g., cancer treatment, e.g., surgery, additional drug(s) or therapeutic agents), methods of the invention may be administered either simultaneously (as a combined preparation) or sequentially in order to achieve a desired effect. This is especially desirable where the therapeutic profile of each compound is different such that the combined effect of the two drugs provides an improved therapeutic result.

Exemplary cancer treatments include, for example: chemotherapy, targeted therapies such as antibody therapies, immunotherapy, and hormonal therapy. Examples of each of these treatments are provided below.

Chemotherapy

In some embodiments, the methods of the invention are administered with a chemotherapy. Chemotherapy is the treatment of cancer with drugs that can destroy cancer cells. “Chemotherapy” usually refers to cytotoxic drugs which affect rapidly dividing cells in general, in contrast with targeted therapy. Chemotherapy drugs interfere with cell division in various possible ways, e.g., with the duplication of DNA or the separation of newly formed chromosomes. Most forms of chemotherapy target all rapidly dividing cells and are not specific for cancer cells, although some degree of specificity may come from the inability of many cancer cells to repair DNA damage, while normal cells generally can.

The methods of the invention may be used with antitumor agents, alkylating agents, antimetabolites, antibiotics, plant-derived antitumor agents, camptothecin derivatives, tyrosine kinase inhibitors, antibodies, interferons, and/or biological response modifiers. In this regard, the following is a non-limiting list of examples of additional agents, e.g., additional therapeutic agents, that may be used with the methods of the invention.

Targeted Therapy

In some embodiments, the methods of the invention are administered with a targeted therapy. Targeted therapy constitutes the use of agents specific for the deregulated proteins of cancer cells. Small molecule targeted therapy drugs are generally inhibitors of enzymatic domains on mutated, overexpressed, or otherwise critical proteins within the cancer cell. Prominent examples are the tyrosine kinase inhibitors such as Axitinib, Bosutinib, Cediranib, desatinib, erolotinib, imatinib, gefitinib, lapatinib, Lestaurtinib, Nilotinib, Semaxanib, Sorafenib, Sunitinib, and Vandetanib, and also cyclin-depdendent kinase inhibitors such as Alvocidib and Seliciclib. Monoclonal antibody therapy is another strategy in which the therapeutic agent is an antibody which specifically binds to a protein on the surface of the cancer cells. Examples include but are not limited to, the anti-HER2/neu antibody trastuzumab (HERCEPTIN®) typically used in breast cancer, and the anti-CD20 antibody rituximab and Tositumomab typically used in a variety of B-cell malignancies. Other exemplary anbitodies include but are not limited to, Ctuximab, Panitumumab, Trastuzumab, Alemtuzumab, Bevacizumab, Edrecolomab, and Gemtuzumab. Exemplary fusion proteins include but are not limited to, Aflibercept and Denileukin diftitox. Targeted therapy can also involve small peptides as “homing devices” which can bind to cell surface receptors or affected extracellular matrix surrounding the tumor. Radionuclides which are attached to these peptides (e.g., RGDs) eventually kill the cancer cell if the nuclide decays in the vicinity of the cell. An example of such therapy includes BEXXAR®. In some embodiments, the targeted therapy can be used in combination with the methods of the invention.

Anti-Inflammatory Agents

The methods of the invention can be administered with an anti-inflammatory agent. Anti-inflammatory agents include, but are not limited to, non-steroidal anti-inflammatory agents (e.g., Salicylates (Aspirin (acetylsalicylic acid), Diflunisal, Salsalate), Propionic acid derivatives (Ibuprofen, Naproxen, Fenoprofen, Ketoprofen, Flurbiprofen, Oxaprozin, Loxoprofen), Acetic acid derivatives (Indomethacin, Sulindac, Etodolac, Ketorolac, Diclofenac, Nabumetone), Enolic acid (Oxicam) derivatives (Piroxicam, Meloxicam, Tenoxicam, Droxicam, Lornoxicam, Isoxicam), Fenamic acid derivatives (Fenamates)(Mefenamic acid, Meclofenamic acid, Flufenamic acid, Tolfenamic acid), Selective COX-2 inhibitors (Coxibs) (Celecoxib), Sulphonanilides (Nimesulide).

First-Line Therapy

The present invention describes a method of treating a human subject having cancer, wherein the subject has failed (e.g., relapsed from, insensitive to, received no or little benefit from) first-line treatment (e.g., first-line therapy for cancer). The present invention also describes a method of treating a human subject having cancer, wherein the methods of the invention are administered with an additional agent. In some embodiments, the additional agent is a first-line therapy for cancer.

First-line therapy is typically the first treatment given for a disease (e.g., cancer as described herein). It is often part of a standard set of treatments, such as surgery followed by chemotherapy and radiation. When used by itself, first-line therapy is generally the one accepted as the best treatment. If it does not cure the disease or it causes severe side effects, other treatment(s) may be added or used instead. First-line therapy is also called induction therapy, primary therapy, and primary treatment.

For example, first-line-therapy, e.g., for Hodgkin lymphoma may include: Adcetris (Brentuximab Vedotin), Adriamycin PFS (Doxorubicin Hydrochloride), Adriamycin RDF (Doxorubicin Hydrochloride), Ambochlorin (Chlorambucil), Amboclorin (Chlorambucil), Blenoxane (Bleomycin), Bleomycin, Brentuximab Vedotin, Chlorambucil, Clafen (Cyclophosphamide), Cyclophosphamide, Cytoxan (Cyclophosphamide), Dacarbazine, Doxorubicin Hydrochloride, DTIC-Dome (Dacarbazine), Leukeran (Chlorambucil), Linfolizin (Chlorambucil), Lomustine, Matulane (Procarbazine Hydrochloride), Neosar (Cyclophosphamide), Procarbazine Hydrochloride, Velban (Vinblastine Sulfate), Velsar (Vinblastine Sulfate), Vinblastine Sulfate, Vincasar PFS (Vincristine Sulfate), and Vincristine Sulfate.

In some embodiments, first-line-therapy, e.g., for Hodgkin lymphoma comprises administration of a combination of therapeutic agents, e.g., therapeutic agents as described herein. For example, the combination may comprise Doxorubicin Hydrochloride (Adriamycin), Bleomycin, Vinblastine Sulfate, and Dacarbazine (i.e., ABVD). As another example, the combination may comprise Doxorubicin Hydrochloride (Adriamycin), Bleomycin, Vinblastine Sulfate, and Etoposide (i.e., ABVE). In some embodiments, the combination comprises Doxorubicin Hydrochloride (Adriamycin), Bleomycin, Vinblastine Sulfate, Etoposide, Prednisone, and Cyclophosphamide (i.e., ABVE-PC). In some embodiments, the combination comprises Vincristine Sulfate, Doxorubicin Hydrochloride (Adriamycin), Methotrexate, and Prednisone (i.e., VAMP).

Approved therapeutic agents and combinations for different types of cancer can be found on the National Cancer Institute at the National Institutes of Health Cancer website at http://www.cancer.gov/cancertopics/druginfo/drug-page-index

Second-Line Therapy

The present invention describes a method of treating a human subject having cancer, wherein the subject has failed (e.g., relapsed from, insensitive to, received no or little benefit from) second-line treatment (e.g., second-line therapy for cancer). The present invention also describes a method of treating a human subject having cancer, wherein the methods of the invention are administered with an additional agent. In some embodiments, the additional agent is a first or second line therapy for cancer. Second-line therapy generally refers to treatment that is given when initial treatment (e.g., first-line therapy) does not achieve a desired result, e.g., does not work, is not efficacious; stops working. Second-line therapy is typically considered or given when a subject does not respond or develops a resistance to initial treatment (e.g., first-line therapy). For example, second-line therapy is typically considered or given to a subject with relapsed or refractory disease.

EXAMPLES

The disclosure is further described in the following examples, which do not limit the scope of the claims.

Example 1 FAK/PYK2 Inhibition Enhances Efficacy of Immune Checkpoint Inhibition

The small molecule FAK/PYK2 inhibitor VS-6063 is shown to inhibit monocyte-derived macrophages, decreases IL-6 and IL-8 production from macrophages in vitro, and reduces tumor-associated macrophages in xenograft models. Additionally, in contrast to other protein kinase inhibitors, such as the SRC inhibitor dasatinib and the MEK inhibitor trametinib which potently impair the proliferation of CD8+ cytotoxic T-cells, VS-4718 and VS-6063 stimulate proliferation of CD8+ cytotoxic T-cells (FIG. 1). Primary human CD8+ T-cells isolated from healthy donor PBMCs were incubated in the presence of anti-CD3/anti-CD28 coated beads with increasing concentrations of VS-4718 or VS-6063 for 72-hours and assayed for BrdU incorporation as a measure of new DNA synthesis. Both FAK inhibitors dose-dependently increased CD8+ T-cell proliferation.

Based on the inhibition of tumor-associated macrophages and enhancement of CD8+ T-cells, potentiation of FAK/PYK2 inhibitors on the anti-tumor efficacy of an anti-PD-1 monoclonal antibody in syngeneic mouse tumor models was investigated. Mice bearing established syngeneic MC38 colorectal tumors were treated with VS-4718 for 5 days before combination treatment with anti-PD1 antibody along with continued VS-4718 administration. Combination of VS-4718 with anti-PD1 extended the median overall survival to 42 days relative to 21, 25 and 28 day median overall survival with vehicle control, single agent anti-PD-1 and single agent VS-4718, respectively (FIG. 2). Moreover, on day 56, 30% of mice treated with the VS-4718/anti-PD-1 combination were still surviving compared to no surviving mice in the vehicle, single agent VS-4718 and single agent anti-PD-1 groups.

FAK kinase inhibitor or FAK genetic ablation each induced full tumor regression in a Squamous cell carcinoma model through an immune mechanism, suggested by an increase in CD8+ and CD4+ T-cells, and a decrease in T-regs.

The general pattern of immune cell changes in response to FAK inhibitors emerged across syngeneic models of skin, pancreatic, lung, and breast cancers. Increased cytotoxic T-cells were observed in tumor (for example, the CD8+ T-cell population). A decrease in immune cell populations that suppress anti-tumor immune response (for example, T-regs, M2 tumor-associated macrophages, MDSCs) was also observed. A pattern of an increase in PDL1-High tumor cells and an increase in PD-1 and cytotoxic T-cells was also seen. The data suggests synergy between FAK inhibitors and immune checkpoint antibodies (anti-PD-1 anti-CTLA-4) in multiple tumor models.

Example 2 Efficacy of FAK Inhibitors with Anti-PD-1 and Correlation with Biomarkers

Mice bearing syngeneic MC38 tumors were randomized once tumors reached 50-100 mm³ and treated with either vehicle, VS-4718 (75 mg/kg, BID, p.o. through end of experiment), anti-PD1 (clone RMP1-14, 10 mg/kg i.p. on days 1, 4, 8, 11) or VS-4718+anti-PD1. Median tumor volume over the days elapsed is shown in FIG. 3A. The combination of VS-4718 and anti-PD1 improved anti-tumor efficacy in syngeneic MC38 colorectal tumor-bearing mice.

Syngeneic MC38 tumors were randomized once tumors reached 50-100 mm³ and then treated with either vehicle, VS-4718 (50 mg/kg, BID), anti-PD1 (clone RMP1-14, 5 mg/kg on days 1, 4, 8, 11) or VS-4718 + anti-PD1 for 12 days at which point tumors were processed live for flow cytometry (FIG. 3B-D). VS-4718 and anti-PD1 combination in MC38 tumors decreased Tregs and increased CD8+ T cells.

Syngeneic MC38 tumors were randomized once tumors reached 50-100 mm³ and then treated with either vehicle, VS-4718 (75 mg/kg, BID, po), anti-4-1BB (clone LOB12.3, 10 mg/kg i.p. on days 1, 4, 8, 11) or VS-4718+anti-4-1BB. Mean tumor volume is plotted over time in FIG. 4. The combination of VS-4718 and anti-4-1BB improves anti-tumor efficacy in syngeneic MC38 colorectal tumor-bearing mice.

CD8+ T cells were isolated from fresh, healthy human PBMCs by negative immunomagnetic bead separation. Purified CD8+ T cells were plated on CD3-coated plates in the presence or absence of VS-4718, VS-6063, or GSK2256098 for 72 hours. Assay wells were pulsed with BrdU for the last 3-4 hours of culture and subjected to a BrdU-incorporation assay for the determination of actively proliferating cells. Data shown in FIG. 5 are presented as fold-change vs. DMSO control wells.

CD8+ T cells isolated from fresh, healthy human PBMCs by negative immunomagnetic bead separation were plated on anti-CD3 coated plates in the presence of VS-4718 (FIG. 6A) or VS-6063 (FIG. 6B) for 72 hours and then harvested and stained with anti-LAG3 or anti-PD-1 for flow cytometric analysis.

FAK inhibitors change the tumor immune balance to potentiate efficacy of various immuno-oncology agents. FAK inhibitor combination substantially enhances anti-tumor efficacy of anti-PD-1 or anti-4-1BB vs. each immuno-oncology antibody alone. FAK inhibitor+anti-PD-1 combination decreases Tregs and increases CD8+ T cells in MC38 tumors. FAK inhibitors increase CD8+ T cell proliferation, decrease CD8+ T cell exhaustion markers, and increase T cell-mediated tumor cell killing in vitro.
